Bruce St. Laurent, a local officer helping with security for the president’s campaign visit, was preparing to shut down Interstate 95 ahead of the president’s motorcade when he was hit by a Ford F-150. He was pronounced dead soon after being transported to St. Mary’s Medical Center.

Palm Beach County Sheriff spokeswoman Teri Barbera told NBC that an investigation was ongoing, but no charges had yet been filed against the truck driver who hit St. Laurent.

The president didn't see the accident, White House press secretary Jay Carney told NBC, but when he learned of St. Laurent’s death he said, “our thoughts and prayers are with the officer’s family.”
